摘要：
A fuel pressure control apparatus includes a valve for controlling an internal pressure of a fuel tank, the valve including a valving member, a valve seat, and an actuating member for pressing the valving member on the valve seat under a set pressure; and a pressure adjusting part for adjusting the set pressure of the actuating member of the valve to a first set pressure when an engine is operating, the first set pressure being higher than an atmospheric pressure and allowing the internal pressure of the fuel tank to be in equilibrium with the first set pressure, and for adjusting the set pressure of the actuating member to a second set pressure when the engine stops operating, the second set pressure being higher than the first set pressure, thus allowing the internal pressure of the fuel tank to be increased, when the engine stops operating, to a pressure higher than the first set pressure.
